To all whom t may concer/n.'

Be it known that l, JAMES 0. Bewan", a

citizen oi' the United States, residing at luusta, in the county of Richmond and the lotate of Georgia, have invented certain new and useful Improvements in Thermos-Urns, ot which the following is a speciiication.

This invention relates to urns designed to receive liquids to be kept heated kor cooled, and more especially `ior urns oi the type found in lunch rooms, cafs, boarding houses etc. and intended to hold coi'ee, cocoa, or other beverages.

ln many smaller towns there is no gas supply to keep such urns or their contents heated. The urn is also, in proper size, especially suited to boarding houses as it can be placed on the table and the contents will retain practically their original temperature, when placed in the urn, until withdrawn tor use.

rihe invention consists of the novel features of construction hereinafter described, pointed out in the claims, and shown in the accompanying drawing, in which:

The figure is a vertical section taken through one ot the urns, centrally and horizontally broken away.

n. the drawing 1 designates an outer casing or tank surmounted by any form oie. ornamental top, and which may be nickel or silver plated or given any desired finish.

It is provided with suitable supporting legs 2. Arranged within but out o t direct Contact with said tank or casing is the urn proper, indicated at 3. It is braced by side braces 4C and supported above the bottom of the casing by supports 5. Leading from the top` of the urn and extending downwardly to the lower portion of thelcasing is a vent pipe 6. A glass filler gage 7 is arranged at the side ont the casing being supported at its upper end by a bracket and locknuts 7 a, and carries a removable 'tunnel 9. The gage proper terminates below the level of the top of the urn so that no liquid can rise high enough to enter the vent pipe 6. On the side of the casing is a suitable housing 10 which supports the lower end oi' the gage and with which the gage communicates.

,A supply pipe for the .liquids indicated at 8 leads vfrom the bottom of the urn and extends into the housing and is provided with a branch that extends upwardly and receives the lower end of the gage glass. The

pipe l is preferably Jformedl in two `sections, one within the casing 'and'onefwithin thehousing 16, and-the `casing is lperforated fas at 8a Vto give communication between the said sections..` hand valve 11 works in the housing and leasing, the" inner end being threaded as at 12,'iand this-valve stem `carries aidisk orvalve 13 normally covering and closing the perforationsFlfL.` "A draincockld is provided for the gage 7 vand 'also for that'portion ofthe pipe 8 within the housing 10.

The ventpipe 6 also extends through the housing, opening outwardly through the housing end. This opening is normally closed by a leaf spring, the inner face of which may carry aclosure pad of vany kind, the spring having its lower end secured to .the lower margin of the housing and having its upper end extending above the housing and curved to form a thumb grip by means of which the spring may be drawn outwardly thereby unclosing the air vent pipe.

The casing also carries, preferably on the side opposite the gage 7 a housing 17 to which leads a vent pipe 16 similar to the one at 6. Mounted in the housing 17 is a discharge faucet 19. A discharge pipe 20 leads from the bottom of the urn to said faucet. The faucet has an air vent bore 21 and a discharge bore 22, which register respectively with the pipes 16 and 2O when tlieiaucet is turned into open or discharge position.

An air vent 18 is formed in the housing 10.

The operation of the parts above described is as follows To fill, the spring'l is drawn back, valve 13 being first opened, and the liquid is poured into the funnel 9. It passes through the gage, and through pipe 8 intothe urn 3, the liquid standing in the gage indicating the height to which `it rises in the urn, the air in the urn escaping through the pipe 6. The spring is then released closing the vent 6, and the valve 13 closed.

The liquid remaining in the gage and housing may then be drawn off through the cock 14 if desired. If at any time after a portion of the urn contents have been used it is desired to lmow how much remains this can be found out by merely opening the valve 13. The liquid will then stand in the gage at the same level as in the urn, and the valve 13 can then be again closed.

It will be understood that a vacuum is Eaten ted ov. 9, 1920.

sol

created vand maintained at all tirnes in the space between the easing and the' urn. When liquid is to be Withdrawn Vfrom the urn the'l 'faucet 19V is turned so that the bore Y 22 and also the bore 21 register' respectively with `the pipes 2O and 16, this permits flow of airthrough the opening V18 and through bore 2l and pipe 16 tothe interior of the urn, andeseape of liquid Vfrom the urn `,through pipe 2l.
